ynew and useful Improvements in Combined Picture-Projecting and Sound-Reproducing Machines, of which the following is a speciication containing a full, clear, and exact description, reference bein had to the accompanying drawings, orming a part hereof.

My invention relates to an improved self-- contained instrument for the production and transmission of sound, and more particul larly to the transmission of speech in connection with moving pictures and their visual display.

The o b'ect of my invention is to provide an improved single instrument, in which shall bevcontained and combined in comaphophone, Victrola, or other common orm of talking-machine, and a moving-picture projector, as well as a suitable screen upon which the pictures will be exhibited to audiences, in the home, `or in halls.

My invention consists in the novel construction and combination of the several parts as hereinafter described and particularly designated in the claim found at the end of this specification.

In the drawings,

Figure 1 is a top plan view of an instrument embodying my combination (in one form) of-a talking-machine, a moving-picture projecting machine, and a screen movably mounted to slide upon the frame of the machine.

2 is a sectional side-elevation ofthe machine or instrument, the section being taken on the line 2--2 of Fig. 1.

Fig. 3 is a detail sectional lan-view of the combined horn and screen s 1de chamber, the section being taken on the line 3-3 of Fig. 4 is a detail transverse vertical section, taken through the talking-machine and its combined horn and screen-slide chamber, on the line 4-4 of Fig. 1.

Fig. 5 is a detail vertical section of a p0rtion of the inner vertical wall of the combined horn and screen-slide chamber, and showi a common lens mounted in an aperture ormed in said wall, and

'jecting machine,

Fig. 6 is a front view of a piece of the picture film.

The numeral 1 designates a suitable baseframe ,or casing for the support of the comblned talking-machine, movin -picture machine, and combined horn an screen-slide chamber, and which base-frame may be of 4any desired material and exterior ornamenbe best suited to the use of tation, as may or in public the instrument in the home, halls.

A common talking-machine turn-table 2 1s mounted (in the present form of my inventron) upon the usual vertical spindle, and 1s driven by the bevel-gears 3 andhorizontal shaft 4:, sprocket- Wheel 5 and a silent cham 6 of common form, connected to any suitable form of motor 7 bythe sprocketwheel 8 on the motor shaft; all of which parts are located above the combined horn and screen-slide chamber 9, and the latter being locatedabove and supported by the said base-frame 1.

Within said horn chamber 9 is mounted to slide in suitable guides 10, in telescopic relation to the said guides, a combined sliding horn and screen-slide 11.

Said slide 11 extends out of said chamber 9 through a suitable vertical wall 4of said amber, and carries at its'outer end a screen-frame 12, in which is lstretched a common screen 13, of fabric, or any suitable material. I

The .rear (or inner) end of the said combined sliding horn and screen-slide 11 is open, to receive the sounds from a xed-horn 14, located in said horn chamber 9 in the rear of said slidin part 11, and to permit passage of rays o light from the lens 15 which is fixed in the aperture 16 of a vertical partition 17, which separates the said chamber 9 from the projecting-machine chamber 18. (See Fig. 5.)

The talking-machine is fitted for the usual records 19, and has the well-known soundbox 20 and needle, as well as the swinging tapered horn-tube 21, the latter beig connected to the interior of the said fix horn 14 by a fixed vertical tube 22 extending through an aperture formed in the tti??x o said chamber 9 downwardly to the said edhorn.

Within the projecting-machine chamber 18 is located a common moving-picture prohaving the usual lantern plening in the front 23 (which may be of electric or other form) the upper film magazine 24; the lower filmmagazine 25; and the usual film-moving mechanism case 26, as well as the lenstube 27.

. yFrom said film-moving case 26 I extend a horizontal drive-shaft 28' through an aperture in the vertical side-wall of the said chamber 18, and on said shaft I fix a sprocket-wheel 29 over which runs said chain 6, to drive the film-moving mechanism synchronously with respect to the movement of the said talking-machine rec? ord 19. In case it is desired to run the machine by hand, a hand-crank 30 is located on the outer end of said' shaft 28.

In order .to deaden the noise of the machinery as much as possible, so that it will not interfere with the speech and other sounds produced by the talking-machine, I cover the interior of the Walls of the narrow vertical chamber 3l (in which the said sprocket-wheels 5 and 8 and a great part of the sprocket-chain 6 are located) with a series of superposed layers of sound-deadening padding 33; and besides I line the internal walls of the projecting maohlne chamber 18 with the same, or similar, material, in order that the noise of the running machinery therein will be confined as much as possible to that chamber.

With my machine, as above described, the standard moving-picture lm 32, or a smaller film, may be used; but on all films I provide a startin mark 34, drawn or imprinted transverse y of the film at the starting-point, to accurately inform the operator of the exact location of the first picture to be exhibited synchronously with the appropriate sounds produced by the talking machine record, which latter is also provided with a starting mark 35 on its face, to register with a flxed mark 36 made on the upper face of the said turn-table 2.

The operation of my invention will be obvious to those skilled in the art.

It will reproduce the music of any musical-instrument, or of orchestras and bands, as Well as talking-sketches, vaudeville, operas, and all other sounds produced bythe human voice, simultaneously and in synchronism with appropriate pictures of moving objects on saidscreen 13.

Vand produce a realistic effect in connection with the pictures shown on said screen.

The projecting-machine moves in positive synchronism withthe talking-machine; both starting at the same time from a definite starting-point marked on the film and on the record.

The machines, combined as above-described, Will be simultaneously driven by a single motor, which may be supplied with electricity from the ordinary electric-light wires of the h'ouse, or from a common battery; or a hand-crank, or a common springmotor with the usual governor, ma be made use of to drive the combined mac ines.

What I claim is:

a large screen, or directly' In a combined picture-projecting and sound-reproducing machine, a casing having an opening in its front, a combined sliding-horn and screen-support mounted to slide in said opening of the casing, a screen carried by the outer end of said combined sliding-horn and screen-support and disposed across said opening, a picture-projecting machine in the rear of said casing and adapted to project a picture onto said screen, and a sound-reproducing device supported above said sliding-horn and screen-support and having a horn which connects with the interior of the said sliding-horn and screensupport and thereby directs the sound waves downwardly and forwardly into the said sliding-horn and screen-support.

In testimony whereof, -I have signed my name to this specification, in presence of two subscribing witnesses.

JOSEPH MOLTCHEN.
